Refer to the exhibits. The main flow contains an HTTP Request in the middle of the flow. The HTTP Listeners and HTTP Request use default configurations.
A web client submits a request to the main flow's HTTP Listener that includes query parameters for the pedigree of the piano.
What values are accessible to the Logger component at the end of the main flow?

A. payload

B. payload
pedigree query params

C. payload
producer var

D. payload
pedigree query params producer var

C. payload
producer var

In this case as outbound call is made using HTTP: POST /child , all attributes will be replaced by this invocation. Hence query parameter will not be accessible at logger. Hence correct answer is option 2.

Refer to the exhibits.

How are multiple conditions used in a Choice router to route events?

B. To find the FIRST true condition, then distribute the event to the ONE matched route.

C. None of these

D. To find the FIRST true condition, then route the same event to the matched route and ALL FOLLOWING routes

B. To find the FIRST true condition, then distribute the event to the ONE matched route.

Explanation:
Choice router finds the FIRST true condition, then distribute the event to the ONE matched route.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.1/choice-router-concept
The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route’s execution and the others are not checked. If none of the expressions are true, then the default route executes.

Refer to the exhibit.

A. Option A

B. Option B

C. Option C

D. Option D

B. Option B
